Reel Expansion Feature
The initial reel window is three symbol positions high.
If a Key scatter symbol is displayed on any reel, that reel expands to six symbol positions high.
Following the reel expansion, the Key symbol will be removed from the reels, and all empty reel spaces are filled with symbols that fall in from above, in sequence.
Reel symbols that fall from above contain all symbols, with the exception of Key symbols.
It is possible for more than one Key symbol to land on the reels, but only one Key symbol may be displayed on each reel of a given spin.
All symbols continue to fall into empty reel spaces until no more Key symbols appear on the reels.
Wins are evaluated once, after the reel expansion and all symbols have fallen. The reel window remains six symbol positions high on the following spin.
On subsequent spins, the reel height decreases one position on each spin, until it reverts to three symbol positions high.
If a Key symbol hits on the subsequent spins, that reel expands to six symbol positions high and the sequence resets.
Reel heights in the base game are saved separately for each bet level and remain between play sessions.
Mystery Symbol Feature
The reels may contain Mystery symbols on any spin, and they will transform into any symbol excluding Key, Bonus, or Wild symbols.
All Mystery symbols on all reels transform into an identical symbol.
After all symbols have transformed, wins will be evaluated.
MultiWay Xtra Feature
There are 243 to 7,776 ways to win on every spin via the MultiWay Xtra feature, based on the Reel Expansion feature.
Starting from the leftmost column, MultiWay Xtra wins pay for matching symbols in any position in adjacent columns.
If there is more than one matching symbol in the same column, the award will be multiplied.
The Wild symbol substitutes for all symbols, with the exception of the Key, Mystery and Bonus symbols.
On each spin, you will only be paid for the highest paying MultiWay Xtra win for each symbol.
Free Spins Bonus
When a minimum of three Bonus Scatter symbols appear anywhere on the reels, you will activate the Free Spins Bonus.
Number of Bonus Symbols
Free Spins Awarded
The Free Spins Bonus is re-triggered when at least two Bonus Scatter symbols are displayed in any position on the reels.
Number of Bonus Symbols
Extra Free Spins Awarded
You can re-trigger this bonus a number of times, capped at a limit of 200 free spins per bonus.
The Free Spins Bonus starts with an initial three symbol position-high reel window. During this bonus, the Reel Expansion feature works in the same way as the base game.
The Free Spins Bonus begins with an accumulating multiplier value of 1x. For every Key symbol that lands in the active reel window, you will receive a 1x multiplier value that adds to the accumulating multiplier.
Throughout this bonus, reel symbols that fall from above may contain all symbols, and Mystery symbols have the potential to transform into Key symbols.
More than one Key symbol may land on the reels, and more than one Key symbol may be displayed on each reel in the Free Spins Bonus, and a 1x multiplier will be awarded by each of them.
All symbols continue to descend until the reels have no Key symbols remaining on them.
Wins are evaluated once for every free spin, following any reel expansions, falling symbols, Mystery symbol transformations, or multiplier increases.
The accumulating multiplier value is used to multiply all wins.
The reels that are active in the Free Spins Bonus are not the same as the reels you will play with in the base game.
Your free spins are played with the same coin value as the spin that triggered the bonus.
The Free Spins Bonus will conclude when you've used your allocation of free spins, or if you've played 200 free spins.
